Sims’ 5 power workoutsErnie Sims is one of the most muscled-up players on the Cowboys. The linebacker has been lifting weights for years, and it’s one reason he’s among the hardest hitters on the team. He likes the weight room. Here are five of his favorite lifts:1“The No. 1 thing I love doing is squats. And when I say squats, I mean deep squats. I love barbell. Barbell squats.”2“Dead lifts. I like dead lifts.”3“I like lunges.”4“I like doing military press. Any type of dumbbell press.”5“Of course, I like my guns looking good. So biceps and triceps.”Pushed enoughAfter more than two weeks, the first fight of camp broke out. Running back Lance Dunbar didn’t like the way linebacker Ernie Sims slung him to the ground, and everybody rushed in to separate them. “It’s been happening all camp. I’ve been letting it slide,” Dunbar said. And it took this long to get worked up? “Yeah. I don’t have a temper,” Dunbar said. “It takes a lot to push me, to get me going. But when I’m mad, I’ll stand up for myself.”Seen and heardGrammy winners Los Lonely Boys and actor Dennis Haskins, who played Principal Belding on Saved by the Bell, were on the sideline for practice, chatting up owner Jerry Jones and linebacker Sean Lee, among others. Lee told the San Angelo band: “I’m amazed by your talent. That’s something I could never do. I have no musical skill at all.”Helmet popRunning back Phillip Tanner said the reason his helmet comes off is because he tries to make it the only thing defenders can grab. “That’s how I protect myself,” he said. “I drop my helmet down between my shoulders. That’s the only thing for defenders to grab. I try to make it less room for them to hit, and they just seem to grab the helmet.” Two years ago, Tanner’s helmet also popped off in a preseason game. “It comes off so fast, you can’t even feel it,” he said. “As soon as I spin up out of it, it’s off.”Mom, Chevy, apple pie, AmericaThe preseason opener between the Cowboys and Dolphins averaged 10.1 million viewers, and it scored a 17.0 rating in DFW. It was no surprise to Cowboys coach Jason Garrett. “People love football. I think our country loves football. Certainly, the state of Texas loves football. It has a great following. I think people were antsy to see football again, and that’s fun. It’s fun to be a part of something like that.”They said it“He was a good player — a really good player — in college, had a great sophomore year. He fell in the draft. But he’s a good player, and now he’s seeing an opportunity. You don’t want to be home watching daytime soaps.” — Defensive line coach Rod Marinelli on George Selvie“It’s hard to just watch football. You want to go out there and play. I just can’t watch football and not be out there. I’ve just got to keep being patient and keep getting mental reps.” — Wide receiver Terrance Williams on having to wait out a concussionInjury report LB Alex Albright, back, day-to-day OT Demetress Bell, conditioning, day-to-day DT Landon Cohen, eye, day-to-day DE Tyrone Crawford, Achilles’, out for season OG Ray Dominguez, shoulder, 1-2 weeks S Matt Johnson, ankle/foot, 1 week OG Kevin Kowalski, knee, 2-4 weeks OG Nate Livings, knee, 2-4 weeks OT Jermey Parnell, hamstring, 1-2 weeks DT Jay Ratliff, hamstring, 1-2 weeks DE Anthony Spencer, knee, 2-4 weeks WR Terrance Williams, head, day-to-dayNumbers game 1,947Attendance for Tuesday’s practice, the fewest of camp, bringing the camp total to 41,341.
